coverage adjustment.

Masking:
Opaque adhesive tape is supplied so
that sections of the sensor’s lens can
be masked to restrict coverage in
unwanted areas.
COVERAGE PATTERN
Coverage is shown as tested in a controlled setting with the unit mounted at 8ft at a 10° tilt from
the horizontal surface. The actual outside coverage pattern may vary substantially at the specific
installation site and is dependent on several factors including weather conditions, external light
sources, mounting height and sensor tilt.
DESCRIPTION
The EW-205 sensor is an outdoor passive infrared (PIR)
motion sensor rated for wet conditions. It installs
onto a standard round outdoor junction box using
the supplied junction box cover plate.
The EW-205 sensor uses advanced PIR
technology and a superior lens design to
detect motion. PIR sensing is passive, and
detects the difference between infrared
energy in motion and the background
space.
The EW-205 sensor provides a +24VDC
control output upon motion detection.
This output can be connected to a WattStopper
power pack for on/off lighting control, or to a
WattStopper DM-105 or DM-115-WP Outdoor HID Bi-Level control
module for high/low control.

MOTION SENSOR PLACEMENT
Careful consideration must be given to sensor placement. PIR sensors detect the difference
between infrared energy in motion and the background space. To be detected, a person or vehicle
must be within the sensor’s coverage pattern and have an unobstructed view of the sensor.
Mounting Options
• Install onto a standard 4" round outdoor junction box.
• Mount to a flat, stable, vibration-free surface.
• Mount vertically or horizontally, usually to a wall, ceiling or under an eave.
Vertically mounted
The sensor comes assembled and ready for vertical
cover plate mounting, as shown in the illustration on
the right.
Horizontally mounted
For horizontal mounting, such as under eaves, rotate the sensor housing as shown in the
diagrams below. Make sure that the gasket is seated properly.

WIRING AND INSTALLATION
The EW-205-24 can be powered from either a WattStopper Power Pack, or a WattStopper HID
Dimming Module.
• Each WattStopper B series power pack can supply power for up to 11 sensors.
• Each WattStopper BZ series power pack can supply power for up to 15 sensors.
• Each DM-105 or DM-115-WP module can supply power for up to 2 sensors.
When power is initially applied to the sensor, or following restoration from a power failure, the
lights will turn on. If no motion is detected by the sensor, the lights will remain on/high for for
approximately one minute and then turn off/low. (See Security Override, page 9.)
Sensor Wire Functions
The EW-205-24 has 3 wire connections to the power pack or DM-105 or DM-115-WP module.
See the descriptions and wiring diagrams that follow for connections to each specific power
source.

TESTING AFTER INSTALLATION
To facilitate coverage testing, the factory setting for Time Delay is 12 seconds, and the Light
Level is at Maximum.
If you want to test a sensor for intended detection or operation:
1. Make sure that the time delay is set to 12 seconds and the light level is set to maximum
(clockwise to the sun icon). The dials are located on the bottom of the sensor.
2. Adjust sensor to the desired position.
3. Ensure that power has been restored to the sensor.
4. Move into the location to be tested; lights should turn on (or switch to high if connected to
a DM-105 or DM-115-WP HID Bi-Level control module). Stand still. In about 12 seconds
the lights should turn off (or switch to low if connected to a DM-105 or DM-115-WP
HID Bi-Level control module). Move or walk and the lights should turn on/high. Repeat
this process to test other locations. Make sensor coverage adjustments as needed (see
Coverage adjustment and Masking, page 2).
Note: When power is restored to the sensor, the lights will turn on/high for approximately
one minute. (See Security Override, page 9.)
Note: If the lights do not turn on/high with movement in the area after they have
turned off/low in step 4, the level of daylight may be too high and the sensor’s light level
adjustment is keeping the sensor inactive. Wait until daylight levels have reduced before
testing again.
5. See Dial Adjustments, below, for guidelines to adjust the time delay and light level to the
desired settings for operation.
DIAL ADJUSTMENTS
Time Delay and Light Level control dials are located on the bottom of the
sensor.
1. Adjust Time Delay:
The time delay is the amount of time that elapses before lights turn
off since the sensor last detected motion. This can be set from
12 seconds to 16 minutes. Typically, the time delay should be set to
1 minute or more.
• In areas where there is mostly walk through movement, the time
delay amount can be low.
• In areas where people may stop and remain for periods of time,
the time delay should be set to a higher amount, preferably
16minutes.
2. Adjust Light Level:
Turning the light level adjustment dial raises or lowers a light level
detector in the sensor. When the light rises above this set level, the
sensor becomes inactive; this keeps the lights off when there is
enough light present.
We suggest initially setting the light level adjustment to half way between
minimum and maximum. If a different setting is desired after installation,
then follow the Making Changes procedures, next page.

Making Changes
If you want the lights to turn on/high sooner—turn the light level dial toward the sun icon, as
desired; this raises the light level setting. (Remember, the sensor must detect motion for lights
to turn on.)
• The lights turn on/high sooner in the evening.
• The lights stay on/high longer in the morning.
If you want the lights to turn on later—turn the light level dial toward the moon icon, as
desired; this lowers the light level setting. (Remember, the sensor must detect motion for lights
to turn on.)
• The lights turn on/high later in the evening.
• The lights turn off/low sooner in the morning.
Notes:
• When testing adjustments, make sure not to block any of the light that is reaching the
sensor or reflect any light into the sensor’s lens.
• The sensor requires about 5 seconds for light level adjustments to take effect. This feature
prevents the lights from turning on/high and off/low with quick light reflections, from car
windows for example.
• The sensor will not turn lights off/low until no motion is detected and the time delay
elapses.

9
SECURITY OVERRIDE
The EW sensors have an override-on feature which allows lights to be turned on/high for the set
time delay period.
• If there is an installed switch—turning the switch off then on, turns the lights on/high. If no
motion is detected by the sensor, the lights will remain on/high for for approximately one
minute and then turn off/low.
This will also happen when power is restored after a power outage.
Note: If the lights do not turn on/high, the sensor may be inactive due to the light level. Turn
the switch off for 5 seconds, then turn it on. The lights should turn on/high as described above.
TROUBLESHOOTING
Lights do not turn off/low:
1. The sensor may be detecting movement outside the desired coverage area. The sensor’s
lens may need to be masked to block unwanted coverage (see Masking, page 2). If this does
not solve the problem, see step 2.
2. Test to see that the sensor is operating properly. Set the time delay to minimum (12
seconds). Remain still, or move out of range of the sensor. If there is no movement in the
coverage area, the sensor should turn lights off/low in 12 seconds. Reset the time delay to
the desired value.
3. If the lights do not turn off/low, have a person qualified to check high voltage connections
verify that the sensor and lighting are wired correctly (see Wiring and Installation, page 5 &
6).
CAUTION: Make sure power is turned off at the circuit breaker before checking wiring.
4. If the sensor is wired correctly, call our Technical Support number.
Lights turn on/high when there is sufficient daylight:
Decrease the light level setting, as desired (counterclockwise toward the moon icon, see Dial
Adjustments, page 7 & 8).
Lights do not turn on/high:
1. If there is a controlling switch installed, make sure that it is turned on.
2. If the lights do not turn on/high when lights are needed—increase the light level setting, as
desired (clockwise toward the sun icon, see Dial Adjustments, page 7 & 8).
3. Have a person qualified to check high voltage connections verify that the sensor and lighting
are wired correctly (see Wiring and Installation, page 5 & 6).
CAUTION: Make sure power is turned off at the circuit breaker before checking wiring.
4. If the sensor is wired correctly, call our Technical Support number.
